Question

A) some migratory birds travel as much as 15,000 km to escape the extreme climatic conditions at
home. Write the distance in meters using scientific notation.
B). A new born bear weighs 4 kg. How many kilograms might a five year old bear weigh if its
weight increases by the power of 2 in 5 years?

Answer 1

Answer :

Given : Birds travel as much as 15,000 km
And
We know 1 km = 1000 m

So,

Total distance covered by birds = 15000 $\times$ 1000 = 15000000 m = 1.5 $\times$ 10⁷ m ( Ans )

2 ) A new born bear weighs 4 kg
And
weight increases by the power of 2 in 5 years
So,
Bear weigh in five year = 4² = 16 kg ( Ans )
